a CBDC has advantages over normal digital fiat.
You can't compare those two, they are apple and oranges even if that sounds strange.
Central bank digital currencies are going to replace cash, they won't be an alternative to a digitally represented fiat. A transaction that is done via your bank is an IOU-based. CBDCs won't have any difference from cash other than humiliatingly bad privacy. So, it should be properer to say that CBDCs have disadvantages over, say Bitcoin.
obviously it has many many many disadvantages over bitcoin. i listed a few..
but governments are trying to go "cashless" meaning its not going to be a paper cash + digital cash + CBDC... its just going to be CBDC
but like i also said if it went full 'bank authorised' both in registration and payment sign off. then all 'cash' features are gone. which is the negatives of CBDC
there would need to be a way for people to make their own independent keys with no banker multisig to retain
some "cash" features
If satoshi will appear and will do a patent for blockchain
its too late..
bitcoin went public in 2009 and got good wide public use in 2010. whereby satoshi would have ran out of time (grace period) to file a patent
that said even in 2009 he wanted it open and public, he didnt want to patent it.
and even now he wont gain anything if it were even possible to patent it.
It is really too late right now and in copyright cases anything can happen but I am sure that he will not do that because of the reasons which I mentioned above. He has developed a new style system and the patent will just erode its this feature then it will mean nothing to file a patent.
